Question

a community is considering raising funds to pay for improvements to the community swimming pool. to measure the level of interest, community leaders went door - to - door in a few neighborhoods and interviewed residents. of the 230 residents contacted, 157 support raising funds to pay for improvements. which of the following represents the population in this setting?
○ all residents of the community
○ the 230 residents who were interviewed
○ all residents who use the community pool
○ all residents who support raising funds for the pool

Explanation:

In statistics (a subfield of Mathematics), the population refers to the entire group about which we want to draw conclusions. Here, the community wants to measure the interest of all its residents in raising funds for the pool. The 230 interviewed are a sample, those who use the pool or support are subsets, not the entire population of interest. So the population is all residents of the community.

Answer:

A. all residents of the community
